There are many snacks in general schools. If you want to lose weight, you must first stay away from all snacks. Secondly, don't go on a diet to lose weight. It's no use. Even if it works in a short time, it will rebound and hurt the body. To lose weight, you should eat three meals normally, be full at eight points, and exercise again, and you will definitely lose weight. I do Duoyan Zheng aerobics at school for half an hour every day. I'm tired!
